Summary

CVE-2025-14708 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Sgwbox N3 Firmware. Its CVSS base score is 8.9 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-14708 is a buffer overflow vulnerability (CWE-119, CWE-120) in Shiguangwu sgwbox N3 version 2.0.25. The flaw affects an unknown functionality in the /usr/sbin/http_eshell_server file of the WIREDCFGGET Interface, where manipulation of the "params" argument triggers the overflow. Published on 2025-12-15, it carries a CVSS v3.1 base score of 9.8, reflecting its critical severity.

Attackers can exploit this vulnerability remotely over the network without authentication, privileges, or user interaction (AV:N/AC:L/PR:N/UI:N/S:U). Successful exploitation grants high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), potentially allowing arbitrary code execution. A public exploit is available, increasing the risk of widespread abuse.

VulDB advisories, which serve as the primary disclosure sources, detail the issue but note that the vendor was contacted early without any response, implying no patches or official mitigations are available. Additional references include VulDB submission pages and a Notion document summarizing the sgwbox NAS N3 buffer overflow.
